Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 1260243-04-6, name is Ethyl 5-amino-1H-pyrazole-4-carboxylate, This compound has unique chemical properties. The synthetic route is as follows., SDS of cas: 1260243-04-6
To a solution of sodium ethoxide (520 mg, 7.6 mmol)In EtOH (20 mL)A solution of ethyl 3-amino-1H-pyrazole-4-carboxylate (1 g, 6.45 mmol) and 1,3-dimethyluracil (1.35 g, 9.68 mmol) were added sequentially.After the reaction system was stirred at 90 C for 3 hours,Move to an ice-water bath to cool and precipitate with amber. The filter cake was collected by filtration and washed with water (25 mL). The resulting solution was adjusted to pH = 7 with acetic acid and precipitated as a white solid which was filtered. Toluene (100 mL) was added to the resulting solid and dried in an ether to give the title compound as an off-white solid (900 mg, 67%).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 1260243-04-6.
